Multiple Layer Error Control Over Wireless Links

Category: Software and Web Development, Networking and Communications

Overview This paper compares the wireless performance of TCP with or without selective acknowledgments and in the presence or absence of a reliable link layer protocol, in order to determine whether link layer error control remains beneficial for TCP variants with improved error recovery capabilities, such as TCP SACK. The paper also examines whether there are adverse interactions between the two protocol layers, that is, whether link layer error control degrades the congestion control performance of the transport layer, and whether transport layer error recovery degrades the error control performance of the link layer. The results show that, even with TCP SACK, link layer error control remains critical for TCP performance over wireless links.
